2015 was the world's hottest year ever by a long shot. But what drove the record temperatures, and what role did climate change play?
2015 will likely be the hottest year on record, according to a preliminary analysis released by the World Meteorological Organization.
This has been Australia's hottest October on record. And the record-breaking temperatures are at least six times more likely thanks to human-induced global warming.
An analysis of the world's longest-running temperature record suggests that England is many times more likely to experience more record-breaking hot years like 2014 than it was a century ago.
